swAGING-Toor..

To all whom it may concern:

Be it known that I, ROBERT SCHUEBEL, residing at Littell, in the countyof Lewis and State of Washington, have invented a new and ImprovedSwaging-Tool, of which the following is a specilication.

rlhis invention has for its object to provide an improved tool orimplement by which .theswaging or upsetting operation may be readilyperformed on bolt rodmembers in one heat without removing said bolt rodfrom the machine until finished and my said invention in its genericnature, comprehends an improved construction of tool or implement of thecharacter stated, embodying a suitable support, an anvil bar Xedlymounted on the support and a bolt rod clamping means, adjustably mountedon the frame, in such manner that under one adn justment or setting toproject the head end vertically to provide for swaging or flattening theend and under another adjustment or setting to present the edge of theiattened head end of the bolt uppermost and to rest upon the base oranvil member.

In its more subordinate features my invention consists in certaindetails of construction and peculiar combination of parts, all of whichwill be hereinafter fully described and specifically pointed out in theappended claims, reference being had to the accompanying drawing, inwhich:

Figure l, is a perspective view of my invention, showing the sameadjusted for upsetting or swaging the upper end of the bolt rod. Fig. 2,is a plan view thereof. Fig. 3, is a detail horizontal section of onecnd of the clamping jaws or members, said members being shown as clampedor locked together. Fig. 4, is a similar view, the jaw members beingshown as released and spread by the spring device that coperatestherewith. Fig. 5, is a detail side elevation, the clamp or bolt holdingdevice being shown as set to its vertical position on the frame. Fig. 5,is a detail cross section taken on the line n a on Fig. 5.

line Il ll on FigulO.` Fig. l2, is a view of a modification of the clampscrew shown in Figs. l0 and l1.

In carrying out my invention, I provide a stout frame or support of aheight suitable for supporting an anvil bar l, which, as shown in thedrawings, is bolted on one end of saddle plates 2 2 in turn bolted tothe end standards 3 3, preferably of wood, and that have base or footmembers 30-30 and are strengthened by a metal brace bar 3l bolted at theends to the said standards as best shown in Fig. 5.y

Rockably mounted on the support adjacent to and parallel with the anvill is the clamping means, which is adjustable with respect to clampingthe bolt irons and for holding the irons in either the vertical orhorizontal plane. The clamping means consists of a stout metal bar 5,the opposite ends of which are formed with trunnions 50-50 for engagingthe portions 20 20 formed on the plates 2 2 and which forml solidbearings for the ends of the bar 5.

To permit of turning the bar 5 freely from a horizontal position asshown in Figs. l, 2 and 6 to the vertical position shown in Figs. 5 and5a, the saddle plates 2 2 inside the bearings 20-20 are recessed as at21 to give clearance for the bar 5 when turned in the directionindicated by the arrow a3 on Fig. 6. The bar 5 which also forms an anvilor hammering base, coacts with another clamping member 6, the adjacentfaces of the two bars 5 and 6 having semi-circular seats 51 and 6l ofprogressively increasing sizes for receiving the bolt irons of differentdiameters when the member 6 is closed against member 5, see Fig. l.Clamping member 6 is hingedly connected at one end to the bar 5 byhaving the said end formed with a right-angled reduced extension 62 thatfits the horizontal slot 53 in the bar 5, in which it is held by thehinge pin 54, see Figs. 8 and 9. The other end of bar 6 eX- tends to thecorresponding outer end of the bar 5 so as to rest on the saddle plate 2at that end, which forms a rest for the bar 6. The bar 6 is normallyforced to its open position, see Fig. 4, by a coil spring 7 that is heldin the sockets 55 and 65 on the opposing faces of the bars 5 and 6, andthe bar 6 is readily clamped and held locked to the bar 5 by means of ayoke 8 that is slidably mounted on the two bars 5 and 6, and a wedge key9 that coacts with the yoke in a manner well understood by referring toFigs. 3 and 4L of the drawing, from which it is apparent that shovingthe key to the position shown in Fig. 3 securely clamps and holds thejaw 6 lockedagainst jaw 5 and fmoving the key in theother directionfrees the jaw 6.

From the foregoing taken in connection with the accompanying drawingsthe manner in which my invention is used and its advantages will bereadily apparent.

When it is desired to upset or form a head in a rod, the same afterbeing properly kheated is clamped between the members 5 and 6, whichmembers are then adn justed to the position shown in Figs. l, 2 and 3.The `operator then hammers the upper end to form tion. This being downand while the rod is still hot, the members 5 and 6 are turned to thevertical position, which now lbrings ,theV

rod to the horizontal plane withrone edge of the head'against the anvill, see Fig, 5a. This leaves the opposite edge positioned for fi beingproperly hammered, it being understood that the head being now on therod it need not be tightly clampedand is left to be turned freely tobring the several edges in position for "hammering, which operation, by

the flattened or head por-V reason of the ease and rapidity inwhich thebolt can be handled is done before the rod cools.

If desired, the anvil 1V may carry a clamp Y screw 10 for coacting withthe anvil 1 to` 'clamp kthe iron against the edge of the anvil to kholdit .for being formed as desired, and to facilitate the clamping actionof the screw 10 it may be provided with a swivel bearing head 10X, asindicated in Fig. 12, which bearing head' 10X may be of theordinary typesuch as is used in ordinary clamps..

Having thus described my invention, what I claim is':

The combination with a suitable support,

an anvil bar fixedly mounted thereon; of a bolt rod clamping means,rockably mounted on the support parallel withthe anvil, said' clampingmeans under one adjustment being adapted for sustaining the bolt rod ina vertical position and when rocked in a positionl at right angles tothe first position adapted for bringing the projecting bolt rod end overonto the anvil plate;
